Pimples that have been around for a year and still won’t go away are commonly seen in acne and can be treated through general treatment, medication, physical therapy and other methods.
1. General treatment: patients should pay attention to facial cleanliness, avoid squeezing and scratching the face with hands, and avoid excessive intake of spicy and stimulating foods.
2. Medication: For mild acne, patients can use topical retinoic acid ointment, benzoyl peroxide gel, fusidic acid cream, azelaic acid and other drugs. For moderate to severe acne, oral doxycycline, minocycline, isotretinoin and other drugs can be combined. For female patients with high androgen levels, oral medications such as cyproterone acetate and spironolactone can also be used.
3. Physical therapy: Physical therapy such as red and blue light can also be combined to kill Propionibacterium acnes and reduce inflammatory reactions.
If the symptoms of acne do not go away after a year, it is recommended to consult a doctor and follow the doctor’s instructions for medication.
